Well, spoke to Tom at CC tech support today and he felt like it's the ESC...so it's a waiting game for my replacement to arrive, none in stock at the moment...he also checked on my replacement MMMV3...

When I look at the graph for maximum ripple the voltage is 24.1, so calculated ripple is 8.0, which is still reasonable...I'm worried about the cogging...I just have a feeling my lipo has gotten old?...
